A structural connection device is disclosed and is formed of a plurality of hub components having extending ear pairs for connecting with elongated struts or the like for constructing spatial structures. The hub components are positioned in stacked abutting relationship and connected into a unitary device via a single elongated rod connector disposed through and sealed within a large single axially aligned perforation extending centrally through each of the hub components. Adjacent hub components are rotated relative to each other prior to assembly to provide an angular relationship between the respective ear pairs of adjacent hub components. The elongated rod connector 16 (FIGS. 1-2), and 16a (FIG. 3) is fixed to the hub components by shrink fitting, force fitting or adhesively bonding. Other connection embodiments utilize a key-keyway arrangement (FIGS. 4-5a), a cross-pin arrangement (FIGS. 6-7a) and a star or gear shaped connector element (FIGS. 8-9). Custom angled ear pairs are provided by utilizing a center connector element having a rounded end 117 and bolting one or more ear pairs 119 thereto at the desired angular relationship (FIG. 12).
